Jacksonville, VT 05358 Frost Dates
When can you plant in Jacksonville, VT?
Typically, the last spring freeze lands around 05/14, roughly 259 days out. The first fall frost typically arrives around 10/04, about 143 frost-free days later.
Jacksonville sits in USDA Zone 5b (-15 to -10°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.
What to do before the first frost
About 5 weeks of growing season left in Jacksonville before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 05/14 isn't a guarantee
05/14 is the middle of 30 years of NOAA records, not a promise. Plant by 04/30 and you're betting against frost in roughly 9 years out of 10. 05/26 is the safer bet, historically only a 1-in-10 chance of frost that late.
